The Taiwan calendar works exactly like the Gregorian calendar, except that the year and era are different. The TaiwanCalendar class recognizes only the current era.

Note

For information about using the TaiwanCalendar class and the other calendar classes in the .NET Framework, see Working with Calendars.

Leap years in the Taiwan calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

The Taiwan calendar has 12 months with 28 to 31 days each:
